# C1179 — Specify the whole-genealogy extension before execution

## Question

Which extra local source change must join the post-Flood dictionary to cover MT andLXX completely?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1178",
  "File18 §4A",
  "C1154"
]
```

## Results

```json
{
  "whole_genealogy_next_model": {
    "path": "model/whole_genealogy_extension_question.json",
    "sha256": "826ee1186994592063674adc6bdb4c228acf9a60b905f281e5bdecfbba031b8e",
    "bytes": 546
  },
  "extra_life_coefficient": [
    {
      "name": "Lamech",
      "delta_b": 0,
      "delta_L": -24
    }
  ]
}
```

## Finding

Lamech’s−24 is the only additional pre-Flood lifespan change needed. The proposed complete model will compare four shared coefficients against the less constrained five-parameter alternative, keeping its fitted Eber relation visible.

## Reassessment

Assess the first block’s gains against its unresolved source burdens before the required full Strategy reread.

## Checks

```json
{
  "onlyLamech": true,
  "ordinaryNoahunchanged": true
}
```
